Anyone else can follow up to the archivist to confirm ([email protected]), but below is verbatim what I received:

That episode was scheduled to be FRONTLINE #2908 but was pulled from the schedule. I don't have information at hand as to why it was pulled, but it is listed as "never aired" in our system. We don't have any copies of the program in the archives.

PBS has started referring to Frontline episodes by season number instead of year. This might be a retroactive change so I don't know if the mods want to stick with the original format. I'd prefer to keep it as is just so I don't have to manually rename 700 files.
